Serial No. 660,991.

To all whom it may concern:

Be it known that I, ALVA B. SMITH, a citizen of the United States, and aresident of Memphis, in the county of Shelby and State of Tennessee,have invented a new and Improved Shade-Support, of which the followingis a full, clear, and exact description.

My invention relates to shade supports, and it has for its object toprovide one with two telescopic members having brackets for carrying ashade roller, each of the members having lugs around which a cord isdisposed so that the members are held firmly to the cord when the cordis drawn taut, the cord being disposed around pulleys which are mountedto permit of the cord being conveniently drawn taut, and the pulleys being so supported that they may be readily removed and replaced.

Other objects of my invention will appear in the following completespecification, in which the preferred form of the invention isdisclosed.

In the drawings similar characters of reference indicate correspondingparts in all the views, in which- Figure 1 is an elevation showing awindow frame provided with my improvement; Fig. 2 is a sectional View onthe line 2-2 of Fig. 1; Fig. 3 is an enlarged view showing how the shaderoller brackets are supported by the cords; Fig. 4 is an enlargedsectional view on the line 1-1 of Fig. 1; Fig. 5 is a perspective viewshowing the studs used to support the roller shown in Fig. 1; Fig. 6 is.an elevation, partially in section, showing a modified form of theinvention; and Fig. 7 is a sectional view on the line 7 -7 of Fig. 6.

By referring to the drawings it will be seen that each of the brackets5, which are secured near the bottom of the window frame 6, is providedwith two vertical channels 7 and 8, the terminal 9 of the stud 10traveling in the channel 8, and the said stud 10, at its bent portion 11traveling in the vertical channel 7. This stud 11 is bent downwardly, asbest shown in Fig. 2 of the drawings, and it has a threaded terminal 12,which extends through an opening 13 in the bottom of the bracket 5. Anut 14L meshes with the thread on the terminal 12 of the stud 10, and asthis nut 14: presses against the bottom 15 of the bracket 5, it tends tohold the stud 10 down and the cord 16 taut, which is disposed on thepulley 17, mounted on the stud 1.0. At the top of the window frame 6 thebrackets 18 are secured, each of these brackets 18 having sides 19 withopenings 20, the sides of each of the openings 20 converging toward thecenter of the window frame. Disposed in the openings 20 in each of thebrackets 18 there is a stud 21, the studs 21 having the transversegrooves 22 for receiving the edges of the brackets at the openings 20 sothat the stud 21 may be disposed in the openings 20 at their widestends, and when the studs are moved toward the center of the windowframe, the grooves 22 in the studs 21 will fit the sides of the openings20, and prevent the studs 21 from becoming displaced. iilounted on thestuds 21 there are rollers 23. The cord 16 is disposed upwardly from theright-hand bracket 5, over the pulley 23, mounted on the stud 21, in therighthand bracket 18, then over the pulley 23 mounted on the stud in theleft-hand bracket 18, then under the pulley 17 mounted in the left-handbracket 5, then up and around the pulley in the left-hand bracket 18,coming out and across from the underside of the left pulley 23 to theunderside of the right pulley 23 then around the right pulley 23 anddown and under the pulley 17, mounted on the stud in the righthandbracket 5.

Ihe shade roller support consists of two telescopic members 24, each ofwhich has a bracket 25, for supporting the shade roller. The members 24:are secured to the cord 16 by means of a lug 26, on each of the members24:, and two lugs 27 on each of the members.

It will be seen by referring to Fig. 3 of the drawings that the lug 26is disposed at one side of the line passing from one of the lugs 27 tothe other, and that the cord 16 is disposed at one side of the members24 and is engaged by the lugs 27, the cord between the lugs 27 passingto the other side of the member 24, and laterally to a position Where itis engaged by the lug 26. l/Vhen the cord is disposed around the lugs 26and 27 in the manner described, and the cord is drawn taut by means ofthe nuts 14-, which draw downwardly on the studs 10, it will be foundthat tl z shade roller supporting members 2 1 will be held securely inposition on the cord 16. One of the members 2 1 is secured to thatportion of the cord 16 which extends from the left side of the leftpulleys 23 and 17, and the other member 2 1 is secured, in the mannerdescribed, to that portion of the cord 16 which extends from the leftside of the right-hand pulleys 23 and 17 as shown in Fig. 6. A hand cord16 is secured to the cord 16, by which means the cord 16 may be movedover the pulleys in the manner well understood. Mounted on the brackets25 in the customary manner, there is a shade roller 28, carrying a shade29.

The construction shown in Fig. 6 of the drawings corresponds in mostrespects with the construction shown in Fig. 1 of the drawings, but itwill be observed that to the terminals 16 of the cord 16*, there aresecured the terminals 30 of a chain 31, this chain passing around asprocket wheel 32, mounted on a stud 33, journaled in bearings 34 in abracket 35. The stud 33 is rotated by a wheel 36 and secured to the studthere is a disk 37 having projections 38 for engaging the head 39 of apin 40. By rotating the wheel 36 the cord 16 may be moved over thepulleys in a manner readily understood, to raise or lower the members 24and the brackets 25, which support the shade roller.

It will be understood that the disk 37 is resilient, and that as theprojections 38 engage the head '39 on the pin 40, they will serve tohold the pin and the cord relatively to the pulleys, until the operatoris desirous of changing the elevation of the shade roller.

Having thus described my invention I claim as new, and desire to secureby Letters Patent:

1. In a shade support a member having a shade roller supporting means,two lugs spaced apart and projecting laterally at one side of themember, and a third lug disposed at one side of a line extending fromone of the first-mentioned lugs to the other firstmentioned lug, andprojecting laterally at the other side of the member.

2. In a shade support a bracket having two vertical channels and anopening at its bottom, a stud disposed across the bracket for travelingin the channels, the stud being bent downwardly and having a. threadedterminal disposed through the opening, a nut meshing with the thread onthe terminal and engaging the bracket, a pulley mounted on the stud, asecond pulley, a cord disposed around the pulleys, and a shade rollercarrying means supported by the cord.

3. In a shade support two brackets each having two vertical channels,and an opening at its bottom, a stud disposed across each of thebrackets for traveling in the channels, the studs being bent downwardlyand having threaded terminals disposed through the openings, nutsmeshing with the threads on the terminals for engaging the brackets,additional pulleys, a cord disposed around the pulleys, two members eachhaving lugs around which the cord is disposed so that when the cord isdrawn taut by turning the nuts against the brackets, the members will besupported by the cord, and shade roller carrying means, secured to themembers.

4. In a shade support a bracket with two sides having openings withsides which converge in one directlon, a stud adapted to be inserted inthe openings at their widest ends, and being provided with grooves forfitting the sides of the openings when the stud is moved toward theother end of the openings, a pulley mounted on the stud, another pulley,a cord disposed around the pulleys, and a shade roller carrying meanssupported by the cord.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. r
